Rooting: the "how to's" and "why for's". This blog can also be thought of as a tutorial. For now, in the Blog Archive (on the right) you'll find a step by step guide to rooting an HTC Hero for Sprint. More phones to come.

You will be told that information will download as soon as you have a data connection. Since you've got one, you can bet that the data is (or has) downloaded.

Step 5) Place your phone on the flat level surface and tap "Calibrate roll and pitch".

You're done. You can now launch Maps (or whatever you use) and snap to your location. If you're outside, it should snap to your location right away with very little margin for error. If you're inside, it should snap to quite quickly with a slightly larger margin of error. Either way, your GPS is working again.

And there you have it.

UPDATE 9/29/2010: It looks like if you disable your GPS, then you'll have to reset and download the GPS state every time you re-enable your GPS. Kind of a pain. Hopefully CyanogenMOD will fix this at some point in the near future.

I've also noticed that if you are slightly underground (like in a garden apartment) you might get an inaccurate lock. That's also kind of a pain... I suppose that this GPS "problem" is the main complaint with Cyanogen and other custom ROMs.
